Building and Using a Network 536 Figure 25.1. A simple network design document, such as this one for a small office network, can aid network design, implementation, and maintenance. Tip Having your network design documented will enable you to expand it more easily when you outgrow it. It is much simpler to determine what needs to be done to expand a network when you see it on paper than it is by looking at it in the "real world." (Besides, unless all the machines are in the same room, you probably won't be able to see them all at the same time anyway.) Building a Network After your network design is complete, you can start building that network. Obtain the devices and cables you need and assemble the network. Your network design document will identify the devices that you need on the network. For example, you can determine the type of Ethernet hub you need by counting the number of devices you are connecting to it and whether it must provide services to the network, such as DHCP server, so that you can share a single Internet account among the devices. You also need to determine the types and length of cable you will need to attach the devices to the network, how the cables will be routed, and so on. To learn more about Ethernet hubs, see "Finding and Installing an Ethernet Hub," p. 608. After you have obtained the devices that will be installed on the network, you need to connect and configure those devices to access the network.
